EDGE-SETTING MACHINE.

Specification of Letters Patent.

Patented Sept. 3, 1918.

Application filed November 14, 1916. Serial No. 131,330.

To all whom it may concern:

Be it known that I, ELI J. GAeNoN, a citizen of the United States, residing at Exeter, county of Rockingham, State of New Hampshire, have invented certain new and useful Improvements in Edge-Setting Machines, of which the following is a speci fication.

This invention relates to improvements in edge setting machines adapted to burnish the edges of the shank and tread of a shoe sole; Such machines usually. consist of a vibrating tool head provided with oppositely disposed tool posts upon which the different tools for operating upon portions of the sole edge of differing contours and thickness are adapted to be interchangeably mounted. The setting of the edge of a shoe sole usually involves two consecutive operations and the use of two difierent sizes and styles of setting tools.

In operating upon the tread portion of the sole edge, the particular tool best adapted for this work is aflixed in the'twin post tool head and is caused to vibrate against the sole edge by the vibrating mechanlsm of the machine, and during its vibration the operative guides the sole edge con .tinuously past the setting tool until he reaches the narrowed inwardly curved portion of the shank of the sole. It is then necessary to revolve the tool head through half a revolution to throw out of operative position the setting tool which had been operating upon the edgeof the tread portion of the sole and to throw into operative position the theretofore idle setting tool of the othertool post and which tool is designed and best adapted for setting the edge of the shank portion. In order to turn the tool head of the usual edge setting machine, it has been necessary for the operative to place one hand over the exposed upper end of the tool head and manually turn it against the resistance of a coiled spring, thereby to throw out of position the one tool and to throw into position the other tool. This required the removal of one hand of the operative from the shoe sole and was a source of inconvenience not only as regards the actual turning of the tool post itself, but as regards the matter of supporting the shoe and maintaining it in proper position to be worked upon by the shank or tread setting tool when said tool was swung into operative position. Owing to the high speed at which these machines are required to operate, and the difliculty of manually rotating the tool head itself, the operative is usually obliged to put down the shoe while turning the tool head to its new position. This involves a delay and momentarily distracts the operatives attention from the operation of setting the sole edge and a corresponding loss of efficiency. Although special edge setting machines have been designed in which it has been possible to turn the tool head without removing the hand from the shoe, such machines so far as I am aware have not found favor in the trade and have not been generally adopted.

It is the object of the present invention to provide a convenient and readily operable mechanism for revolving the tool head from one of its operative positions to the other which will leave free the hands of the operative to support and guide the sole during the operation of changing the position of the tool head. This object is secured in my present invention by roviding a tool shifting device capable of operation by a simple motion which may be imparted by a treadle or the like.- My device is essentially an attachment for the usual edge setting machine and may be attached to practically any edge setting machine upon the market without substantial reorganization or modification of the construction and op-.

eration of such. machines, and in this respect differs essentially from those machines in which this feature of shifting the tool head by means which leave free the operators hands has been included only through a substantial reorganization and modification of the machine itself. In carrying out my invention the tool is given a reciprocatory motion preferably through the instrumentality of a treadle actuated bar and this motion is transmitted as rotary motion applied to the tool spindle by a suitable motion transmitting means, whereby to positively and quickly revolve the tool head through a half revolution.

An illustrative embodiment and the operation thereof in accordance with my invention is fully disclosed in the specification which follows. In the drawings accompanying that specification, I have shown an embodiment of my invention which has been found satisfactory'in use and adapted for practical operation in standard edge setting machines. Throughout this specificafrom the machine, and showing different positions of the'tool posts. 4

Fig. 4! is a partial central section through i the tool head and showing position of the parts in shifting the tool post.

Fig. 5 is a similar section at right angles to Fig.--t and showing the tool post locked in its carrier.

Fig. 6 is a detail view illustrating the mount for the tool head-shifting device, and

Fig. 7 is a detail view of apart hereinafter described.

For the purposes of illustration, I have shown in Fig.1 a. sufficient portion of an edge setting machine of standard construction equipped with my improvement to enable the operation of my invention to be readily understood. It will of course be understood that my improvement is applicable to either single or twin edge setting machines. A

I have indicated generally at 1 the frame of an edge setting machine and at 2 the bed of the head structure. Mounted on one or both endsof the bed plate 2, according to the type of machine, is a vibratory tool head indicated generally at 3., The specific manner of mounting the tool head on the bed and the specific mechanism for vibrating it form no part of the present inven tion and are not therefore shown or described in detailhere'in.

The tool head itself consists of an axial spindle 4 to thelower end of which is fixed in any suitable manner a twin post tool member 5 having diverging tool posts 6 with tool retaining springs or theequivalent devices 7, whereby to detachably support the different edge setting tools. Surrounding the spindle 4L and spaced therefrom is a sleeve 8 terminating'at its lower end in a bifurcated portion 9- adapted to normally straddle the sides of the member 5. Set through one of the overhanging sides of the portion 9 isa stud or equivalent device 10 adapted to fit in" a groove 11 cut in a sleeve 12 fixed to the spindle 4 between and the sleeve 8. i The groove is substantially of double Y-form, the! portions being cut at opposite sides of the spindle, and the upper ends of their forks merging into each other so that there is a continuous annular space above the straight depending portions thereof. The spindle isfixed near its upper end'in'a cap sleeve 13 which is partially received in the sleeve 8. The upper end of the spindle itself is exposed beyond the sleeve 13 for depression by a treadle actuated bar 14 which is fastened in a mount 15 adjustably secured to the bed 2 and cona 153 which slide in slots 154 formed in the downwardly extending portion 155 of the bar 14-. The link 16 of. the treadle is fas+ toned to the portion 155, and the spring 156 for the treadle is fastened at its lower end to the treadle and at its upper end to a hook 157 carried by' the bracket 15l -see Figs. 1 and 6. The downward movement of the spindle 1 and" sleeve 13 yieldingly opposed and the parts automatically returned to normal position by a coil spring 18 confined between the cap sleeve 13 and an internal perforated web .19 formed 011 the sleeve'S and through which the spindle passesand is guided.

Surrounding the sleeve 8 and adjustable circumferentially thereon through a screw 20 and slot 21 isa covering sleeve 22 which is provided at its upper portion with a cutout developed on a curve toprovide a curved guiding edge 23 for the free end of a blade spring or equivalent device 24', fastened to the upper exposed end ofthecap sleeve 13. The purpose of this constructionis to'positi'vely start the tool head in the direction in which it is to turn when the treadle is depressed. i e V,

Theoperati'on of my device is as follows: lVithithe'tool head inposition shown iniFig. 2, a depression of the treadle willtcause the spindle and with it the tool post member and sleeve 12 to move downward as shown in Fig. 3 andi'n this movement to'turn through an arc of 180 whereby to bring into eifective position relative to the sole edge that tool post 6 whichin the Fig; .2 position of the parts is disposed in ineffective position. The actual transmission of the reciprocatory motion of the spindle a as rotary motion applied to the tool post member and the consequent rotation of the tool post member 5 is effected through the engagement of the stud 10 with the groove 11 as the sleeve 12 containing the groove is carried downward with thespindle past the fixed stud. When the spindle reaches the limit of its'downward movement, the coil springl8returns' it and the parts moving with it to their normal positions, but the tool post member 5 has of coursebeen turned. toits new position.

By my invention the operative is enabled to turn the tool post to a new position according to the portion of the sole edge he "wishes to work upon Without removing his hands from the shoe and Without loss of time or attention to the setting operation itself, and consequently Without loss of efliciency.

My improvement is capable of ready application to edge setting machines noW in use and indeed my invention may be embodiedin the tool heads themselves of such machines.
